Generator Problem - Chris - 05-20-2006 14:09

Recently purchased an 83 FC 35SB with the 12.5 diesel generator. With
the generator running, only one leg will work. If I turn the breaker
off inside the generator compartment, the other leg will come on and
the one that was working will turn off. I have not been able to make
both sides run. On 50amp shore both work fine. I have also noticed
that with the bottom leg on, the one that controls the mid and rear
A/C, it always reads less voltage on the AC monitor....any ideas on
whats going on? Are there any other breakers on the actual generator
that I am missing?
Thanks

HI Chris:

Replace both 50 amp breakers in the gen set control box and check the
tightness of the neutral. Then open the back of the Kohler and check the
tightness of L-0/L-1/L-2 mounted on the studs found there. The two 50 amp
breakers should be tied together (handles) so you can only turn off or on
both at the same time. The breakers are the same as home units and can be
found at Lowes/Home Depot/Ace

Thanks Ralph..
Happy to hear that the breakers are available at the local hardware store...
I'll check them out when we work on the Birds next weekend...
Thanks

Ralph,
Thanks for the advice. I pulled the breaker out and one side was fried bad.
Looked like a bad connection...
Replaced the breaker from Lowes for under $8.00...Now generator powers whole
coach fine...not just one section like before...
Thanks again,

Generator Problem - chaunceyboyblu - 07-10-2010 09:43

I am having trouble with the genarator in my 88 pt 40. It is a yanmar. I started
it and it ran for some time normally then shut off. Now it will not start from
any of the switches, I just get a clicking noise from one of the bosch relays in
that little metal box by the gen in the foreward compartment. I replaced that
and it does the same clicking. I can start the genarator by jumping across the
starter while holding the throttle solonoid in a bit, but it stopps as soon as I
let go. I checked and there is no voltage at the solonoid while it is running.
Also there is now power in the bus while the genarator is running. Any ideas?

Robert, just got in from being out today. Ralph may have an idea on this dillema. It sounds like an electrical issue, but I don't know. One thought, what is the condition of your generator battery? Mine was fair at Q this year, but was so weak it would not start the generator. Replaced that and all is well.

Hi Robert:

The fuel solenoid is what your holding slightly to run the generator. There
are several things that will be the reason for it not to pull in. So here
go a few questions to you;

1. Is there voltage on the coil of the start relay located on top of the
starter?
2. Does the starter actually try to turn the engine over?
3. Check the fuse or circuit breaker on the control box?
4. Check the coolant fluid level?
5. Check the oil level?
6. checked to be sure wire did not come off the high water temp switch? and
grounding some where. or hwt switch failed closed.
7. Wire off the oil pressure switch?
Answering the questions are the first steps to be taken, I write the checks
down as I go to keep track of where I have been

Now then, with the engine running, you say there is no output from the gen
set? and does your Coach have a manual or automatic transfer switch?

Further checks;
1 As Ernie said, check the state of the gen battery
2 check the diode on the curb side down by the oil pressure sender.
3 Check the bearing in the end bell, does it move up and down greatly with
a screw driver used as a pry bar?
4. Is a wire broken off one or both brushes on the slip rings?
5. is the diode and fuse on the quadrature windings ok?

Answer those questions and we can go further

Safe travels,

Ralph, so I went back out to check a few things. The starter will not run at all
from any of the switches. The battery is new and 12.9 volts. I checked at the
top of the starter and it is 12.9 there as well. When I jump across the two
large posts on the starter the gen starts and runs as long as the actuator is
held in. When I switch the coaches manual power switch from 50 amp to gen. there
is no power in the coach. I checked the coolant level and oil level and checked
for any disconected wires on anything ion the engine. There is only a small 10
amp fuse on the control box and that is okay. The items you listed under
further checks I am not at all familiar with. Am i over my head with this
already, or is there anything I can check? Thanks for your help,
Robert

Nah, not over your head yet, your doing fine.

Now then we know the battery is ok and the starter is running, now we need
to get 12 vdc to the small terminal on the starter solenoid sitting on top
of the starter. So place your mater red lead on the terminal and the black
on a ground and set the meter to dc volts. Check the voltage on the small
terminal when you flip the start switch on the control box, you should see
12 vdc? If you do see 12 vdc then the starter solenoid is suspect, and if
you don't see the 12vdc then we trace back to the point of where we lose
it, and I will have to go get my schematic for the Yammar.
